Cochlea-inspired tonotopic resonators
Dal Poggetto, Vinícius F.; Bosia, Federico; Urban, David; Beoletto, Paolo H.; Torgersen, Jan; Pugno, Nicola M.; Gliozzi, Antonio S. (Peer reviewed; Journal article, 2023)The cochlea has long been the subject of investigation in various research fields due to its intriguing spiral architecture and unique sensing characteristics. One of its most interesting features is tonotopy, the ability ... -
Polarization-driven reversible actuation in a photo-responsive polymer composite
Urban, David; Marcucci, Niccolò; Wölfle, Christoph Hubertus; Torgersen, Jan; Hjelme, Dag Roar; Descrovi, Emiliano (Peer reviewed; Journal article, 2023)Light-responsive polymers and especially amorphous azopolymers with intrinsic anisotropic and polarization-dependent deformation photo-response hold great promises for remotely controlled, tunable devices. However, dynamic ... -
Tunable topological edge modes in Su-Schrieffer-Heeger arrays
Chaplain, G.J.; Gliozzi, A.S.; Davies, B.; Urban, David; Descrovi, Emiliano; Bosia, F.; Craster, R.V. (Peer reviewed; Journal article, 2023)A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtain a device whose operating frequency can ...
